Application led March I'IIBI; Serial No. 550,037.

To all whom it may concern:

Be it known that I, GEORGE L; STONE,

a citizen of'the United States, of America,

yat

residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Phonog followingto be a f ull, clear, and ezliact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to phonogra-phs and its object is to provideimproved means for pivotally mounting the horn -or sound conveyer of the phonograph and to provide a device having various new and useful featureshereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of a device embodying my invention mounted in a cabinet with parts broken away to show the construction; Fig. 2 a front elevation of the same; Fig. 3 a plan view with the top removed; Fig. l an enlarged detail of the joint in the neck of the horn; Fig. 5 an enlarged detail of the upper pivot of the horn;

Fig. 6 a detail of the upper pivot plate; Fig. 7 a detail of the lower pivot plate; and, Fig. 8 a sectional detail of the lower pivot.

Like numbers refer to like parts in all of the Figures.

1 represents a case or cabinetof suitable dimensions and preferablyv provided with doors 2 to close or open this front thereof. Substantially the lower hallf of the CaSe is provided with a series of drawers 3, which are arranged to slide out either at the front or at the rear of the case and are adapted to serve as receptacles for the records.

At the front of the upper part is an open ornamental fretwork 4. surrounding the open end of the horizontal bell 9 of the horn or sound conveyor. This bell is reduced somewhat at the sides of the front edge to permit of pivoting the horn close to the fretwork' at the top and bottom and to allow it to swing laterally at the rear on the pivots hereafter described.

5 is a shelf to support the phonograph or sound reproducing or recolding means 7;

ra'phs; and I do hereby declare theA and this shelf is preferably mounted on vertically adjustable 'brackets 6 to adapt the same to different sizes of machines.

8 is a transverse bar extending across the cabinet in front of the phonograph to locate the same and in conjunction with this are other'adjusting plates 8 at the ends of the machlne, and at 8J at the rear of the machine. These plates are removable to insert and remove the machine and adapted to engage and hold the'machine in fixed relation and pxrper position relative to the other pa1`ts.,\'i`he rear plate 8h has a segmental slot] 3` therein "through which the neck 1l of thehorn projects -and swings horizontally about the axis of the pivots. A vertical plate 8Ii fits-closely the bar 8, and the top and sides of the cabinet; s0 that the cabi' netisk divided into two compartments, one of which contains the reproduce'r 7" and the record support 7, and the other of which contains the bell of the horn.

The horn extends beneath the shelf 5 and is thence curved upward to extend vertically` through the slot 8; Near this 'slot this vertical portion is provided with a joint, as illustrated in Fig. 4, whereby the upper end may be readily detached as occasion requires, and whereby also the upper end 11 of the neck of the horn is permitted to oscillate aboutits vertical axis.

To adapt the small end of theneck 1l"` to move in a right line to conform to the movement of the reproducer along the cylindex' on the machine, the upper end of the neck is bent from vertical to horizontal in a direction substantially parallel with the cylinder, and is thence again bent laterally in a horizontal direction with the small end directed forwar" .substantially at right angies to the axis `,f the record support and cylinder and coupled to the reproducer by a Hexible tube 12 in the usual manner. Thus as the horn swinV on its pivots at the front or open end of thi bell, this bent upper end of the neck will oscillate on its vertical axis and permit the small end which is eonnected to the reproducer to move in a right line, the flexibility of the coupling l2 being Sullicient ,to permit the forwardly projecting end to turn slightly out of the right-anglo, position relative to the axis of the cylinder.

At the top and bottom of the opei end of the bell 9, I insert verticelpivot pins, each being adjustable vertically in thehorn, preferably by screwllhreads thereon, but for a limited adjustment the upper pivot pin may be fixed.V The lower pivot pin 13'is pointed and rests in' a socket in a pivot plate 16 and the upper pin is inserted in aslotted pivot plate 15, whereby the horn oscillates about the vertical'axis of these pins, and a forward movement; of the pin 14 in the slot in the plate 15 permits raising the rear end of the horn to transfer the reproducer clear of the cylinder to starting position. The plates 1 5 and 16 irreV secured to the cabinet adjacent the upper and lower portions respectively ofthe fretwork. During the Vforvf'ard'movenient. of the horn, the latter moves abolita horizontal axis through the point of the pivot pin l13.

The rotative joint 10 comprises an out.- wardly projecting flange 20 Von the upper end of tliepart 11provided with openings or .recesses at regular intervals through which inwardly projecting lugs 19 ona siii'- rounding band 18 are inserted, and the upper part 11l thus rotatively mounted and ield in posit-ion when the lugs 19 are turned` 'under the flange 20 and is readily detached by turning the lugs opposite said openings.

From the foregoing'tlie operation of my device is obvious without further description.

It is to be understood that many modifil cations may be made in the specific structure disclosed above without departing from the spirit of my invention.

That I claim is:

In a device of the class described, the combination with a cabinet, of a repr'oducor and a record support, n sound conveyor ex tending rearwariilly from said reproducer, llien downwardly past said record support and terminating in a forwardly directed ainplifyini;r exit portion arrangedl within said cabinet, und :1 mounting t'or s aid con veycr permitting oscilla-tion thereof about :i vertical axis without movement transverse to said axis, said mounting comprising pivot means :Oiictin f with said exit portion.` substuiitially as iescribed.
